Here is Avalon Hill's Kriegspiel from 1970 with all rules Basic and Advanced incorporated.
Also included is “Advanced Kriegspiel Theory” (Variant Discussion) by Mike Shefler, an excellent variant that truly is better than the original game. (Article originally appeared in Volume 10, #2 of Avalon Hill's The General magazine.)
The module is setup for 2-player or solitary play, with attack and defense done either by choice or randomly.
Enjoy this classic from the early 1970's.
